IMPROVEMENT IN REGISTERS.

Specification forming part of Letters Patent No. 192,792, dated July 3, 1877 application filed May 22, 1875.

To all whom it may concern Be it known that I, ALFRED SHEDLooK, of the city of New York, county and State of New York, have invented a certain Improved (lounter or Register, of which the following is a specification This counter is designed to be attached to printing-presses, to indicate the number of impressions run off, but can be used in all places where a counter or register is required. It is positive in its action, and can be readily adjustedso as to bring the 0 on each of the number-wheels opposite the sight opening in the case.

In the accompaying drawings forming part of this specification, Figure 1 is a perspective view of the improved counter. Fig. 2 is an end View with the end cover removed. Fig. 3

is a sectional view out through the line a; m, Fig. 4; and Fig. 4is a longitudinal sectional view out through the line y y, Fig. 2.

The case a is cylindrical in form, and is cast with one end complete, also with the feet a and the projection 0. extending the whole length of it. The object of this projection will be explained hereinafter. Into the open end of the case a is fitted the head a which is held therein by screws. The shaft b works in bearings in the center of the closed end of It projects beyond the outside of the case at one end a suflicient distance to allow the adjustable actuating-rod c to pass through it. Said rod is held firmly in the shaft by the screw 0. The rod 0 has a hole at one end of it, by which it is connected to any suitable moving part of the machine or press to which the counter is attached, and

the rod is adjusted so that the shaft 17 shall receive an oscillating motion of a little more than one-tenth of-a revolution. The return movement of the shaft is obtained by means of the spring d, one end of which is fixed to the head of the case and the other end to the shaft.

The indicating-wheels e e are bored out so as to revolve on the shaft 1). They are a little smaller than the inside diameter of the case a. They are all alike, and are chambered out on one side, thus leaving a flange through which are drilled ten holes equidistant apart, and

on the periphery between the holes are stamped the cardinal numbers from 1 to 0.

There is a longitudinal opening in the case a, through which one number of each of the wheels are seen, and by which the wheels are reached so as to be set.

In the projection a of the case a are fitted the spring locking-pawls f f, which slip into the holes in the peripheries of i the indicatingwheels 0 0, thus locking them securely and preventing them being moved until the pawls are raised. The pawls are provided with knobs to enable them to be raised by hand when it is required to set the wheels at zero, or any particular number.

On the shaft 1), within the chambered space of the units-wheel, is pivoted the pawl g, which works into the inside of the hole in which the locking-pawl f is, thereby pushing the lockingpawl out of the hole and allowing the unitswheel to be turned until the locking-pawl falls into the succeeding hole, so that for every 0scillating motion of the shaft 1) the units-wheel is turned the one-tenth of a'revolution.

On the side of the units-wheel is pivoted a pawl or dog, h, of peculiar construction, which is controlled in its action by the shaft 1). It

is somewhat of a bell-crank shape, one end of it being provided with a projection, h, which fits into the holes through the periphery of the next wheel, or tens-wheel, when the pawl h is turned on its pivot. This can only take place when the pawl It is under the retaining or locking pawlf, as the shaft b is cut away so as to allow the tail end h of the pawl h to move nearer to the center of it, the pin b causing the pawl h to move on its pivot, pushing the retaining or locking pawl f, which holds the tens-wheel out of the hole in the periphery of the wheel, thus locking the units and tens wheels together, so that as the unitswheel is moved the tens-wheel moves with it, the pawl f falls into the succeeding hole of the tens-wheel and again locks it. The pawl h on the units-wheel is unlocked from the tenswheel when the shaft 1) moves back, and is held in this position by the tail end It sliding round on the perfect part of the shaft b.

All of the indicating-wheels e e, excepting the last one, are provided with pawls h h, and

all ha e the retaining 0-1- leaking paivls ff.

Thecombination of the'retaining orlock'ing They'are operated the same as the w-heel'sjust pawls'ff, wheels 0 e, paw-ls h h, and shaft b,

above described; so it is unnecessary to further describe them.

In the drawings are shown five indicatingwheels, registering-up t0 ninety nine-thOusand nine hundred and ninety-nine, but any number of wheels may be so arranged to register to any desired number.

What I claim, and desirete secure by Letters Patent, is-

constructed and operating substantially as hereinbefore set forth.
